Poor reaction by United; they bottle it in France (9)
I believe the answer is:
cointreau
'they bottle it in france' is the definition.
The definition suggests an adverb but the answer is not.
'poor reaction by united' is the wordplay.
'poor' indicates an anagram.
'by' means one lot of letters go next to another.
'united' becomes 'U' (abbreviation as in Man U for Manchester United).
'reaction' is an anagram of 'cointrea'.
'cointrea'+'u'='COINTREAU'
Can you help me to learn more?
(Other definitions for cointreau that I've seen before include "Sweet orange-flavoured colourless liqueur" , "Alcoholic drink" , "Orange liqueur" , "A sweet orange-flavoured liqueur for cautioner" .)
